Garden tool and control box thereof

Abstract

A control box and a garden tool fitted with the control box. The control box includes a self-propelled trigger unit including a self-propelled control switch S, a lever and a control handle matching with the self-propelled control switch S; and a casing being provided with a receiving cavity. The self-propelled triggering unit is at least partially disposed in the receiving cavity. The lever abuts and triggers the self-propelled control switch S when the control handle is pulled to abut the lever and the control handle swings up and down in a plane where a side wall of the casing is located. The control box has reasonable switch distribution and is easy to operate.

The invention claimed is:

 a casing being provided with a receiving cavity for partially receiving the self-propelled trigger unit; 
 wherein the lever abuts and triggers the self-propelled control switch S when the control handle is pulled to abut the lever and the control handle swings up and down in a plane where a side wall of the casing is located. 
 
     
     
       2. The control box according to  claim 1 , wherein the control box further comprises:
 an activation unit including a main motor control switch B, an activation button, a slider and a first elastic member for resetting the slider, the slider abutting and triggering the main motor control switch B under the action of the activation button; and 
 an operation triggering unit including a main motor control switch A, an operating handle, and a second elastic member for resetting the operating handle, the operating handle abutting and triggering the main motor control switch A when pulled; 
 wherein the main motor control switches A and B, the slider, the first elastic element and the second elastic element are received in the receiving cavity, and the activation button and the operating handle are at least partially received in the receiving cavity. 
 
     
     
       3. The control box according to  claim 2 , wherein the casing is provided with a guiding member, and the slider is provided with a fitting member cooperating with the guiding member, and wherein the slider slides along the guiding member under the action of the guiding and fitting members. 
     
     
       4. The control box according to  claim 2 , wherein the activation button comprises a pressing portion and a push rod connected to the pressing portion, and wherein the push rod is coupled to the slider and pushes the slider to slide when the pressing portion is pressed. 
     
     
       5. The control box according to  claim 2 , wherein the operating handle comprises a first handle and a second handle respectively located at two sides of the casing, and wherein the first handle is provided with a positioning post, and the second handle is provided with a displacement slot cooperating with the positioning post, and wherein the second or first handle synchronously rotates under the action of the positioning post and the displacement slot when the first or second handle is pulled. 
     
     
       6. The control box according to  claim 5 , wherein the upper surface of the casing is located in a first plane, and wherein the first and second handles swing back and forth in the first plane. 
     
     
       7. The control box according to  claim 1 , wherein the control box is also provided with a third resilient element for resetting the control handle. 
     
     
       8. The control box according to  claim 1 , wherein the control box is further provided with a speed control unit, and wherein the speed control unit comprises a speed control knob and a variable electronic component, and wherein the variable electronic component is provided with a driven gear, and the speed control knob is provided with a driving gear matching with the driven gear. 
     
     
       9. The control box according to  claim 8 , wherein a fourth elastic element is further disposed between the speed control knob and the casing. 
     
     
       10. A garden tool, comprising: a handle and a control box as described in  claim 1 ; wherein the control box is fitted on the handle and obliquely facing the user.
